For this, the TV has to have some sort of built-in hard drive, or possibly consumers will be provided some sort of external flash drive or hard drive to feed the content to the TV. However, in any case, this definitely solves the initial problem of buying a 4K TV with out any native 4K content to watch it on. It may also give Sony a way of figuring out an on-going 4K delivery system that is practical and affordable for use with, hopefully, any 4K TV - that would go along way to advance 4K TV adoption.
More details on this development will be known in the next couple of weeks as the initial shipments of the XBR-84X900 are delivered to customers that pre-ordered it. With a list price about $5,000 more, and actual street selling price of about $8,000 more, than the LG 84LM9600 Ultra HD 4K TV that is already being sold in limited markets, Sony customers certainly deserve something a little extra, especially given Sony's current financial woes. It would be great if this became an ongoing offer to purchasers of this set.
